This project aims at providing a deep learning algorithm to detect COVID-19 from chest CT using weak label. And the souce code of training and testing is provided. If you have interests about more details, please check our paper (IEEE Transactions on Medical Imaging).

Before running the code, please prepare a computer with NVIDIA GPU, then install Anaconda, PyTorch and NVIDIA CUDA driver. Once the environment and dependent libraries are installed, please check the README.md files in 2dunet and deCoVnet directories.

• In the directory of "2dunet", the code mainly aims to segment the lung region to obtain all lung masks.

• In the directory of "deCoVnet", the code does the classification task of whether a CT volume being infected.

• In the directory of "lesion_loc", the code mainly implements the lesion localization.

• The file "20200212-auc95p9.txt" contains the output probabilities of our pretrained deCovNet on our testing set.

The pretrained models are currently available at Google Drive, unet and deCoVnet.

If you have any other questions, please contact Xinggang Wang.
